Here's another ball physics project I made. It's based on the physics used in my project "Spirograph (using ball physics)" but then I improved the code and I added more colors and made an on/off switch for the colors. INSTRUCTIONS: 1. Click the Green Flag TWO TIMES 2. Use the "Color On/Off" to change the color mode 3. Enjoy watching the simulation The "Color On/Off" button allows you to switch between having everything in color or having everything in black-and-white shades. (I added a ring around one of the balls so it's easier for you to follow a ball without losing track of where it bounces to)
